The correct option is D Ribosomes
Ribosomes are non-membrane bound organelles found in both eukaryotic and prokaryotic cells. In prokaryotes, they are the 70S type and in eukaryotes, they are the 80S type. Ribosomes are the sites of protein synthesis and are called the 'protein factories' of the cell.
Lysosomes, microbodies and vacuoles are membrane bound organelles. Membrane bound organelles are found only in eukaryotes.
